Christina Applegate said on her podcast "MeSsy" that she was misdiagnosed with multiple sclerosis, Variety and CBS News reported.

Why it matters: Applegate has been one of Hollywood's most visible MS advocates since going public with her diagnosis in 2021.

What she said

Applegate returned after a seven-month health break with a two-part episode. She said new technology led to the discovery.

"This may come as great news, but to me, I'm back at square one," she said, according to Variety. She said her doctor told her, "Congratulations, you don't have MS."
